AR can have the potential to replace literally any service that offers itself online. Does that mean casinos would be obsolete? Nope. The platform casinos would use would simply change. Doesn't mean that it isn't an "online casino" anymore lol. And honestly the AR/VR crap we have right now isn't exactly useable as a service imo for big companies yet. Stuff like VR chat became famous because it was a mostly player driven thing so people get to go ham and do whatever. Would probably take decades before we see anything sensible out of it imo.
